Abstract
The seat belt retractor is provided that comprises an electric motor; a spool operatively associated with the electric motor for winding and unwinding a seat belt for occupant restraint; and a controller. The controller can be configured to control a drive of the electric motor based on a seat belt storage starting condition defined by information about a state of the seat belt relative to a vehicle occupant and information about a state of a vehicle door corresponding to the seat belt. The controller can be configured to control the drive of the electric motor to rotate the spool to wind up the seat belt when the seat belt storage starting condition is satisfied and to temporarily stop the rotation of the spool for a time period when a seat belt load acting on the seat belt exceeds a predetermined amount. The time period can be set according to a satisfaction pattern of the seat belt storage starting condition.
